【摘要】 讨论了一种新的去除水中有害有机分子的方法:在水溶液中形成低温等离子体电晕放电,产生具有化学活性的粒子扩散到水中,氧化水中的有机物,在本实验中用的是苯酚。实验测量了这种情况下的脉冲电晕放电的电压和电流波形图,讨论了自由基捕获剂的存在对溶液COD的影响和pH值对降解率的影响,并用气相色谱仪在吸收波长为210 nm处测定脉冲电晕放电处理后的苯酚溶液的色谱图。更多还原

【Abstract】 A new method for removal of organic molecules from water was discussed, a low temperature plasma corona discharge was formed in water. Chemically active particles were diffused into water and the organics were oxidized. phenol was used in this experiment. The pulse corona discharge wares of the voltage and current were measured. The influence of the existence of radical scavengers on COD of the solution and the influence of pH on rate of degradation were discussed. The chromatogram of phenol solution after pulse corona discharge at absorption wavelength of 210 nm by gas chromategraphic detector was determined.更多还原
